The EPA is supposed to review and study existing standards to see if they are adequately protecting public health. The EPA recently(without doing any studies) decided that the existing standard of 84 parts per billion of ozone is not adequate. The were going to lower it to 75 ppb in 2009 but back pedaled when the pubic raised a din and their own science board said it was unnecessary. They set a new level a 60 ppb, which Obama promptly postponed until after the 2012 elections. Apparently it was a bad idea BEFORE the election but is perfectly ok now.
Except that it has a cost. The EPA says a mere extra $92 billion drag on the economy. The Manufacturers Alliance and the Competitive Enterprise Institute have studies showing the true cost at closer to a trillion dollars. This on top of the current $500 billion cost of the current regulations, making us much less competitive in the world market and giving foreign products a substantial price advantage in American stores over that of American manufacturers. The biggest drag will be the substantial fines paid to the government by every manufacturer and county that remains out of compliance. This is pure taxation. The new regulations place 96% of the country is out of compliance with the EPA. Including Yellowstone Park. Seems that volcanos, hot springs and trees all emit those evil volatile organic components that are precursors to ozone.
And grizzly bear farts.
There is a bad smell but it is not coming from the hind end of the bears.
